Singapore Income Tax Calculator 2025

Chargeable income is the amount of your income that is subject to tax after all allowable reliefs and deductions have been applied. These reliefs include CPF contributions, SRS contributions, earned income relief, and other personal reliefs. Your tax is calculated on this chargeable income, not your gross income.

Singapore offers several tax reliefs: Earned Income Relief (up to S$1,000 if under 55), Employee CPF Relief (actual CPF paid), NSman Relief (S$3,000 or S$1,500), SRS Relief (amount contributed), Course Fees Relief (up to S$5,500), Spouse Relief (up to S$2,000), and Parent Relief (up to S$9,000 per parent). You can claim multiple reliefs in the same year.

Yes. The first S$20,000 of chargeable income is tax-free. This means you only start paying tax on income above S$20,000. This is effectively a personal exemption that applies to all resident individuals.

Your marginal tax rate is the rate you pay on your next dollar of income (the highest tax bracket you fall into). Your effective tax rate is your total tax divided by your chargeable income. For example, you might have a marginal rate of 15% but an effective rate of 8%. The effective rate better reflects your true tax burden.

SRS (Supplementary Retirement Scheme) contributions are tax-deductible and can help reduce your tax bill. However, SRS funds are locked up until age 62 (or age 65 with some exceptions). Decide based on your retirement goals and liquidity needs. This calculator shows you the tax savings from SRS contributions.
